This post is really old so hope i'm not questioning into the void, but I am
2-weeks new to django and trying to figure out the final step to insert the
reportlab charts into the django template - the
cookbook<https://code.djangoproject.com/wiki/Charts> entry
is exceedingly clear about views.py and urls.py, but i'm struggling with
the html template.
#views.py
def barChart(request, word_id):
from charts import BarChartDrawing
word = get_object_or_404(Word, pk=word_id)
e = word.choice_set.get(perspective='East')
w = word.choice_set.get(perspective='West')
b = word.choice_set.get(perspective='Both')
data_string = `e.votes` + `w.votes` + `b.votes`
chart = BarChartDrawing(data =[e.votes, w.votes, b.votes],
title=word.word_text)
binaryStuff = chart.asString('gif')
return render_to_response('templates/myapp/barChart.html', {'word': word,
'binaryStuff': binaryStuff)
#urls.py
url(r'^(?P<pk>\d+)/barchart/$', DetailView.as_view(model=Word,
template_name='templates/myapp/barChart.html'), name='barChart')
#barchart.html
{% extends "templates/myapp/base.html" %}
{% block title %}{{ block.super}}: {{ word.word_text }}{% endblock title %}
{% block content %}
<div><img src="{{ binaryStuff }}" /></div>
<a href="{% url templates_home %}">Return to Home</a>.
{% endblock content %}
many thanks,
-dharol
